Title: Microcapsule containing liquid eraser, its production, and eraser containing the same microcapsule
Inventor: SHINTANI MASATOSHI
IPC: C09D10/00
Filed: 1988-11-14
Abstract: PURPOSE:To obtain the title microcapsule stably containing a large amount of a liquid eraser and being useful for obtaining an eraser which does not undergo a decrease in an erasing capability due to volatilization by allowing hollow particles to occlude a liquid eraser and forming films on the surfaces of the hollow particles. CONSTITUTION:Hollow particles (e.g., silica balloons) are allowed to occlude a liquid eraser, desirably, a solvent which can dissolve or swell a vehicle resin of a water-based ink or a drafting ink, for example, a substance containing at least two isocyanate-reactive functional groups (e.g., ethylene glycol) and the hollow particles are added to, for example, a dispersing medium (e.g., cyclohexane). To this dispersion is added an isocyanate compound (e.g., diphenyl diisocyanate) under agitation to form, desirably, a polyurethane film on the surface. In this way, the title microcapsules comprising surface-coated hollow particles occluding the liquid eraser can be obtained.

Title: Ultrasonic obstacle sensor
Inventor: WADA SHUNICHI
IPC: B60G23/00
Filed: 1989-11-06
Abstract: PURPOSE:To perform effective discrimination of an obstacle at the forward part of a road surface and the like by providing an ultrasonic-wave transmitting and receiving means, an average-value operating means, a judging-signal operating means and a comparing means which outputs an obstacle-detection signal when the processed signal exceeds a judging level. CONSTITUTION:A timing command means 1 outputs a command signal P1 to an ultrasonic-wave-signal generating means 2. The means 2 outputs an ultrasonic wave signal V1 and drives an ultrasonic-wave transmitting means 3. Ultrasonic waves Wa - Wc which are transmitted from the means 3 are reflected from a road surface 4 at the slant forward part and received with an ultrasonic-wave receiving means 6. The means 1 forms command signals P2 and P3 with the command signal P1 for transmission as a trigger. When an obstacle 5 is present on the road surface 4, the received signal is amplified and detected in a received-signal processing means 7 and becomes a processed signal V3. An average-value operating means 8 forms an average value V31 of the signals V3 in the section of the received waves extracted with the signal P2 and inputs the average value into a judging-signal operating means 9. In a comparing means 10, the signal V3 is compared with a judging signal V4, and an obstacle-detection signal V5 is outputted.

Title: Optical isolator
Inventor: NISHIYAMA YUUKO
IPC: G02B27/28
Filed: 1989-11-06
Abstract: PURPOSE:To prevent surface reflected light from each optical component from returning to its incidence side and to reduce the size of the optical isolator by forming at least one end surface of a cylindrical magnet slantingly to an optical axis and joining a polarizer or analyzer directly with the slanting end surface. CONSTITUTION:A Faraday effect element 2 is fixed in the cylindrical hole of the cylinder magnet 1 and arranged slantingly to the optical axis P. The end surface of the cylindrical magnet 1 on the side of the analyzer 4 is formed slantingly to the optical axis P and the analyzer 4 is joined directly with the slanting end surface. The polarizer 3 is fixed in the cylindrical hole of the cylindrical holder 5, which is joined with the other end surface of the cylindrical magnet 1; and the polarizer 3 is arranged slantingly to the optical axis P in above joined state. Thus, the Faraday effect element 2, polarizer 3, and analyzer 4 are arranged slantingly to the optical axis P, so surface reflected light beam from those optical components are prevented from returning to the laser light source side. Further, no analyzer holder is used and the whole constitution is therefore reduced in size.

Title: Vertical deflection circuit
Inventor: NARISAWA TOSHIO
IPC: H04N3/22
Filed: 1989-11-06
Abstract: PURPOSE:To obtain a screen whose center position and a size are always the same even if plural video signals different in vertical frequencies are inputted by holding a fly-back rate being a ratio between the vertical fly-back period and the vertical scanning period of a sawtooth signal supplied to a deflection yoke to be constant even if plural vertical synchronizing signals different in frequencies are inputted. CONSTITUTION:When the sawtooth signal Vf1 or Vf2 different in the frequencies are inputted, a power voltage Ea1' obtained when the signal Vf1 whose frequency is low is inputted and a power voltage Ea2' obtained when the signal Vf2 whose frequency is high are set in the relation of Ea1'<Ea2'. Thus, the inclination of the fly-back period of the sawtooth wave signal Vf2 obtained in the output of an amplifier 1 becomes steep compared to that of the signal Vf2 and the fly-back rate being the ratio between the fly-back period and the scanning period becomes the same. Consequently, the same screen can be obtained without the center position and the size of the obtained screen being changed even if two sawtooth wave signals Vf1 or Vf2 different in the frequencies is inputted.

The upper section is inclined lowered, and a drip is formed in an outer wall to form a wall member 140 by the outer wall and inner wall. Through such operation, work including the construction of outer walls can be integrated, and massive irregularity can be formed on the outer wall.

Filed: 1991-11-01
Abstract: PURPOSE:To realize a recording device wherein stripe-patterns of printing caused by feeding of recording medium hardly occur by setting a peripheral length of a paper feed drive roller to be equal to the whole length of a print head and providing a means for moving the print head and the recording medium relatively finely. CONSTITUTION:By setting a peripheral length of a paper feed drive roller 3 to be equal to the whole length of a print head 2 in the direction of row, the paper feed drive roller 3 rotates once all the time when a recording medium is to be sent from a given print band 5 to a next band 6. As a result, cyclic variation of feeding quantity of the recording medium 4 due to eccentricity of the paper feed drive roller 3 is offset, so that the feeding quantity will be constant all the time. Further, by using a finely moving means, difference in the feeding quantity of the recording medium 4 due to irregularity of individual difference of the outer diameter of the paper feed drive roller 3 can be corrected individually, so that a recording with high precision, where stripe-patterns of printing hardly occur, can be realized without bettering precision of parts.
